To all '5i may concern.'

lle it known that l, Hnnnr HOWARD, a

citizen ofthe United States, residing et llevelencl, in the county of Coyaho end f, emule that shown in Patent No. 1,078 841 have consisted of a cylindrical shell immersed in o surrounding tank constituting deep Water inclet. As the shells ere usually incide of leed, the hydrostatic pressure, duc to the depth of the cooling water on the outside of the shell, was so great that the leed shell tended. to buckle inwardly thereby causing leaks end necessitating complete rebuilding o the apparatus. These shells' moreover hoov 'to be mede of thick ce u which the construction fvy end costly, end it was 'found dicult lie these heavy castings. free from sand n which. in4 coiirse ofi time developed serions lecite. 'Y Y`hese objections l have overcome in tl construction shown in the accompanying lng in which:

cooler., and

. 2 is en enlarged sectional View o s,

he cooler proper comprises e shell l, cli is: preferably cylindrical in cross-seo enel which may be made of rolled lead ont one-heli inch thick, e cover 2, and s *ed bottoni 3. The cover 2 may be mede .l terinl siniile'r to that of the cylindrical il m e shell 'l 'rests on the top i of l., suitable iron freine 5 which is provided 2i tapering leed-lined inner well or pon e :forming the bottom portion 8 of the gas chamber. Frame 5 is in turn supported by suitable masonry bese 7 formed centrally ith e Well. 8 into which the bottom 3 of the "1 depends. A suitable leed-lined coltor 9 may he placed in the Well 8 beneath nronno the open lower eno'. 10 of the or cooling oheinher. A. suitable leed- -.incd l1 communicates with the in- 1 is e longitudinal vertical section of' terior of the shell, preferably through the ta ered bottom 3, as shown. i

he gas to be cooled is introduced at the top of the cooler through enopening 12 in the cover 2. The letter sets upon a flaring lined seat 13 supported by the frame 5 through the medium of beams or other standards 14. A. number of openings or monholes 15, one only of which is illustinted, ere provided in the cover- 2 for periodic flushing of the interior of the shell with hose or the like, and to facilitate manipulation o the hose the openings 15 are preferably conical in section es indicated in the drawingn The charecteristics of the cooler which more specifically have to .do with my novel improvements will new be described. It will be noted from the drawing that the cover is so shaped and seated that between it end the seat '13 there is formed e besnl 16 of substantiel depth end capacity. This basin is supplied in any suitable manner With Water which, after e predetermined height is reached, overflows through one or more pipes 17. ln this meneer the cover is maintained sniiicie'fitly cool to withstand the excessive temperntnreslincident to the introduction of the gee into the cooler.

Surrounding the shell 1` ere s. series of superposed annuler troughs 1S, open et the tops thereorn endv converging to lit tightly et their bottoms against the outer side o the shell. A, Witter-tight engagement' is insured preferably by elep-ioint construction such es is illustrated in E i 2 wherein sin ennulsir inclined rim' 19, W iich shuts against the lower and outer surface vo the trough, is provided With e depending coller 20 by which the rim is secured, es by burning or g5 like, to the shell rlhe trou hs nre su ported at their upper edges byl t e standards let. For this purpose annuler bends 21 may be bolted or otherwise secured. to the stendards 14: end receive enges 22 et the topsV of the troughs 18. Each trough commnnicotes with the one next below by Ineens of one or more lead overflow pipes 23. The pipes piercing any one trough are of course not in .vertical elinement. vith the pipes piercingl the ndiecent troughs, and preferably and'. errmiged diametricelly opposite one another es illustrated.

lipe 17 conducts the werden from the fir Stili 18 from which it flows to the succeeding troughs, seriatim, through the overflow pipes 23, as will be readily understood. The hot gas to be cooled, for example sulfur dioxid, enters the chamber at the opening l2 and the cooled gas passes ofi through the outlet 1l.

Preferably adjacent troughs or pockets 18 overlap each other a few inches, as indicated, and the top of each overflow pipe is set about midway between the plane of the top of the trough and the plane ot' the juncture of the rim and shell. This arrangement gives a certain leeway to prevent overflowing of the water at the tops of the troughs and at the same time insures such a level of water that it will overlap the bottom of the next higher trough by, say, u couple oi inches. rl`hus the shell l is completely jacketed with water.

Suitable means, not shown, controlled for example by the flow of the water from the lowermost overflow pipe 23, may be employed to operate an alarm when the flow of cooling-liquid diminishes to a material devree or ceases.

here are numerous advantages attending the use of my improvements. Of' these I may mention the following:

(l) The dangers resulting from stoppage of the water-supply are minimized, since it would be necessary, after the water-supply stops, to actually evaporate off a considerable quantity of water beiore the, danger point would be reached, and this probably would require at least an hours operation;

(2) The arrangement of the troughs afprdls exceedingly good support to the lead s ielr (3) The cover of the cooler serves as a.

water-receptacle, no part being in Contact with the hot which is not water-cooled.

(4)'l`he lead-lined iron pan forming the bottom o the cooler serves as an acid lute and permits removal of mud etc. Without, in` tei"r`ering with the operation of the cooler. This is especially important when burning fine pyrites.

Other advantages will occur to those skilled in the art.

I claim l. A cooling apparatus comprising a metal shell. a cover having a ,gas inlet therein` a closed bottom portion having a gas outlet, a series of superposed annular troughs surrounding the shell and having their lower ends in watertight engagement therewith, a'ud au overflow conduit extending downwardly through the wall of each trough, the

upper end o. the conduit being below theA upper edge of each trough through which it extends and the lower end arranged to deliver cooling liquid to the trough below.

2. An apparatus as claimed in claim l in which the troughs overlap and the upper end of each conduit is above the lower end of the trough above.

3. An apparatus as claimed in claim l in which the overflow conduits of each adj aoent pair of troughs are on opposite sides of the shell.

4. An apparatus as claimed in claim l ture.
